Just got back and have to say that I was most impressed with the boat from the fort to MK it was wondeful, and fast. We took the one directly to MK multiple times and the one to CR one evening as well. Both were great, with wonderful captains. We took the internal bus our first morning becuase our golf cart hadn't been delivered yet, and even having missed the first bus, by meer seconds, the next one came pretty fast and we made it to MK in time for my daughters appt to the BBB at 8:05 with no problem.

Now the buses were good, but honestly having the golf cart was FANTASTIC. Absolutely would not do the fort without it, definately worth the cost if you ask us especially when getting back from MK at 12:30 with two sleeping children.
Also took a bus to AK and while it did take a while to get there becuase of stopping at Blizzard Beach, it was very comfortable and we got to talk to people which was nice. Plus the bus drops you right up front and you don't have to worry about parking and taking the tram. It was definately worth it.
The only bad transportation experience that we had was with the monorail, it took absolutely forever to get from the CR to the Grand Floridian and we were 30 minutes late for our reservations for my daughters B-Day dinner. However the boat captain had assured us that they would seat us with no worries so that helped, but I was very disapppointed with the monorail.
So as far as transportation in and to and from the Fort it is great. Oh and we stayed in the 2200 loop just two cabins away from the bus stop, it was very nice.
